Stability Analysis and Evaluation of QingXi High-Cutting Slope

Rock nature is mainly controlled by joint-fissur, the stability of rock slope is mainly controlled by the joint surface, the destruction of the slope caused wedge instability formed by joint plane cutting. Stereographic projection can analyze simply and intuitively spatial association relations of straight line and plane in geological body, judge high-cutting slope stability and decisive factor of judge stability of high-cutting slope by means of direction and tendency relationship of rock slope and structural plane. This paper uses stereographic projection to analyze and judge high-cutting slope stability formed by artificial mechanical excavation in Qingxi, and decisive factor of stability according to deformation and fracture and the trends in the high-cutting slope regional, puts forward the high-cutting slope control measures and methods to ensure slope stability and security.
